Three new species of Phylloporia (Hymenochaetales) with dimitic hyphal systems from tropical China

ABSTRACT

Three new species of Phylloporia from tropical China are described in this study: P. manglietiae, P. pendula, and P. pseudopectinata. Phylloporia manglietiae is characterized by triquetrous to ungulate basidiomata, with 6–8 pores/mm, a monomitic to dimitic hyphal system, and broadly ellipsoidal basidiospores, 3–3.5 × 2–2.5 μm. Phylloporia pendula has small, imbricate, and pendent basidiomata, with 7–9 pores/mm, a dimitic hyphal system, and broadly ellipsoidal basidiospores, 3.5–4 × 2.5–3 μm. Phylloporia pseudopectinata differs from other species of Phylloporia by its applanate basidiomata, with 8–9 pores/mm, a dimitic hyphal system, and subglobose basidiospores, 3–3.5 × 2–3 μm. Phylogenetic analyses, based on sequences from the D1–D2 domains of the 28S gene and the internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2 = ITS) of the nuc rDNA, support the classification of the three new species in Phylloporia.
